Ralf have confirmed with his friend (the green packer) that some events can occur 4 times a game. But on my version, no event can occur more than 3 times. And he says me that this fact is correct for the C64 and Atari version. Unfortunately, he hasn't any dump because he plays on real system, so i can't check the source code to understand.

Some others version have random generated map or have 4 joysticks support, etc...

So, i need some help to gather these dumps of MULE that we know they are different from the one in the AMO Package. I haven't any dump tool, nor the SIO cable.

I have all the versions from the TOSEC Dat (8 AFAIK) but haven't actually checked them and don't know either how to check them out without decompile a lot of code.

I have an SIO cable and an original copy of MULE from 1983. I've never dumped it but I'll give it a try in the next few days. I've got tools that can find the differences in between two images. The disk image I'm working from is slightly different than the AMO version but identical in terms of actual gameplay code.

From what I've seen in the code there is no way an event can happen more that 2 or 3 times (depending on the event) -- although the table controlling it could be easily hacked. Seems unlikely but who knows.

wow, cool ! Can you tell me if this is easy to dump a floppy disk with the tools and the cable ?. On eBay, there's some SIO cable for sale, do you now better way to have one than eBay ? Or maybe it's easy to build one DIY ?

Yeah, i've seen the same thing. Easy to hack, but without hacking, it's max 2 or 3 times... And i don't think Ralf is mistaken. For sure, there's some different versions floating around us

Back when the first Atari 800 emulator came out (Xformer for the Atari ST by Derek Mihoka) I made an SIO cable for it. That's the setup I used to get the (cracked, XL-patched) disk image I'm currently working with. Unfortunately, the subtle differences between the ST and PC parallel ports makes the cable incompatible with PCs. So a couple of years ago I bought the Sunmark sio2pc board (purchase on eBay from Sunmark) and made a new cable with it. It was very easy to set up and works well. So far I've only used it to recover my personal Atari software. I'm not sure how well it works with copy protected disks.

After the header comes the disk image. This is just a continuous string of bytes, with the first 128 bytes being the contents of disk sector 1, the second being sector 2, etc.

* The "code" is the 16 bit sum of the individual ASCII values of the string of bytes: "NICKATARI". If you try to load a file without this first WORD, you get a "THIS FILE IS NOT AN ATARI DISK FILE" error message. Try it.

Thanks for that but I do mean ATX. That is the format of the dump Atari Frog mentions. ATX supports copy protected disks so it must have some extra disk data embedded in there. I couldn't find any documentation. Apparently ATX files can only be used with a DLL or patched version of Atari800Win.

Atari Frog answers me on the AtariAge forum. I paste here his message:
